It would be nice to have the capability to add another layer of hierarchy above modules in a course, even if it was as simple as having a collapsible Topic header to better organize larger courses. 

For example, I have a very large course that consists of 80+ modules. These modules fall into 11 different knowledge areas. It would be great to partition the course into 11 topics on the course main page, and when the student clicks the topic header the drop-down opens up to reveal the modules within that topic. It would be a much cleaner look. 

Currently, the only alternative is to move the hierarchy to have individual courses as goals within a path to do the same thing; but this becomes cumbersome for the student to navigate and presents a maintenance nightmare if that path has to be copied across organizations.
